 Have you ever wondered who you look like more, your mother or father? The answer can be found in your genes!

TRANSCRIPT

Have you ever wondered who you look like more, your mother or father? The answer can be found in your genes!

The purpose for this project was to learn more about genes and to figure out why people look the way they do.

Page 4: Have you ever wondered who you look like more, your mother or father? The answer can be found in your genes!

1. Get pictures of offspring, their parents, & their grandparents

2. Find out & compare phenotypes of the parents to offspring.

3. Compare grandparents to parents.4. Compare the children's appearance to

grandparents.5. Record the data on the pedigree.

Page 5: Have you ever wondered who you look like more, your mother or father? The answer can be found in your genes!

Does the offspring of two people have more physical characteristics of their mother or their father?

A Gene is a physical unit of heredity. there is about 20,000 or 25,000 genes in the human body.

A pedigree is a chart that tells someone all of the possible known phenotypes.

Phenotypes are physical traits you inherit from you parents.

Genotype is internally coded inheritable information carried by a living organism.

Recessive is when you produce little or no phenotype when occurring in heterozygous conditions with contrasting alleles.

Dominant is when a genetic trait is considered dominant if it is expressed in a person who has only one copy of that gene.

During our experiment, we figured out most of our subjects inherited more phenotypes from their father. Reasons for this is because the mother had more recessive genes than their father.
